This Japanese Samurai Ninja Sword (Ninjato) is skillfully hand polished By Ab Sword for a smooth sheen finish. Made from folded steel that has been folded 13 times to produce 8192 layers, its full tang blade — the blade continues through the handle — is also very sturdy. This folding is crucial: Indigo assures us that the process enhances the blade’s flexibility and sturdiness by an appreciable margin, which makes it rugged and dependable for use. ​

For extra durability the complete blade is oil quenched (heat treated and then rapidly cooled in oil). It is also given a unique treatment so that striking red and black patterns appear all over its surface. (These patterns aren’t merely decorative — they protect the blade from rust, and the color won’t fade unless you decide to sharpen it off.)

When it comes to the sword’s fittings, every detail is thoughtfully crafted. The tsuba (the guard that sits between the blade and handle) features a delicate flower design and is made of brass. It’s paired with a one-piece brass habaki (a collar that fits around the base of the blade, keeping it secure in the sheath) and two copper seppas (small spacers that hold the tsuba in place). The fuchi (a sleeve that covers the top of the handle) and kashira (the buttcap at the end of the handle) are also brass, adding a cohesive, elegant touch.​

The tsuka (handle) is covered in red genuine samegawa (ray skin), which provides a non-slip grip—perfect for practice or display. It’s wrapped tightly with black chemical fiber ito (cord) using the hineri-maki method (a traditional wrapping technique that keeps the cord secure), and two bamboo mekugi (pegs) lock the full tang blade firmly into the handle. For extra decoration, two flower-themed menuki (small ornaments) are added to the handle, matching the tsuba’s design.​

The saya (sheath) is made from sturdy hard wood and finished with a sleek black-and-red high-gloss coat, giving the sword a polished, eye-catching appearance. Overall, this Ninjato is well-crafted and carefully assembled, making it an excellent choice for dojo students needing a practice sword, a unique gift for martial arts or sword enthusiasts, or a striking display piece to showcase Japanese culture.​
